The player has the ability to learn how to hide. This stealth modus makes him invisible to bystanding enemies. Making it easier to avoid a battle.
When in stealth mode, the light of the lantern will go out for a small period of time, so the player has the change to get past a patrolling enemy.
This modus is not permanent so your timing has to be right or there may be a change you get spotted. To make things even more interesting some enemies will be immune to this modus so sneaking past them won’t be easy.
